Traveler sync issues with iOS 12.1

 14 Dezember 2018 09:22:28
Over the last 3 to 4 weeks I have been contacted by some larger Traveler customers with distributed locations and reported on Traveler synchronization problems.

Some iOS devices are affected with all these customers. But not all devices, but usually users whose Domino mail servers are operated a little further away from the Traveler server.


The problem becomes so noticeable that the mail synchronization with the native Apple Mail App suddenly stops at the device and either no new mails are displayed in the inbox or the mail body cannot be loaded.


After various checks and traces on Traveler, Domino and network side it looks as if the cause is in iOS 12.1.
Yesterday Apple confirmed to one of our customers that the problem is known and they are working on a fix which will probably be released with iOS 12.1.2.


Here is the Apple Statement:



We have released iOS 12.1.2 beta 1, which contains a fix for the issue where Mail messages are slow to load, show "Loading" and a spinning gear. At this time, we are requesting customers to download the beta software from our Apple developer site, to ensure the behavior has been resolved. If the problem triggers on devices running this Beta please collect the sysdiagnose logs and send them as soon as possible.


If you need further information, please contact me.


Update 18.12.2018:

Looks like the fix did not made it into iOS 12.1.2 GA.

A fix is now mentioned in the new iOS 12.1.3 Beta Resolved Issues list.
